CAR-BURETER ATTACHMENT.

Specification of Letters Patent. Application filed August 16, 1913. 4 Serial No. 785,074.

To all whom it may concern Be it known that we, JULIUS MARTIN and HARRY SIBBALD, both citizens of the United States, and both residing in the borough of Bronx, in the city of New York, county of Bronx, and State of New York, have invented certain new and useful Improvements in Garbureter Attachments, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

Our invention relates to carbureter attachments, and more particularly to .an appliance adapted to be inserted inthe carbureter ofl'take for the purpose of securing a more thorough admixture of the hydrocarbon and air.

The main object of our invention is to provide an attachment of this character which, without material obstruction of the carbureter oiftake pipe, will agitate and deflect the moving column of hydrocarbon and air in a manner to break up any globules of hydrocarbon and bring a sufficiently large proportion of the hydrocarbon into intimate contact with the air to insure a more thorough admixture of the two, and the production of a highly volatile mixture possessing high combustion value.

A further object is to provide an appliance\ of this character adapted to secure a thorough admixture of the hydrocarbon and air at all engine speeds.

A still further object is to provide an attachment of this character wherein the admixture of the hydrocarbon and air is secured by a mechanism having no movable parts, thus avoiding likelihood of a loss of efficiency through reduced suction or a disarrangement of parts.

A still further object is to provide an appliance of this character wherein the parts will be so arranged as to insure the deflection, division and agitation of the moving column of hydrocarbon and air and the recombination thereof in amore stable mixture, without any substantial diminution in the capacity of the carbureter offta-ke pipe or the engine manifold. 1

A still further object is to provide an appliance of this character which will secure increased, engine efliciency by reason of the more thorough admixture of the hydrocarbon and air, or will secure equal engine efficiency with a reduction in the volume of hydrocarbon entering into each charge.

And a still further object is to provide an attachment of this character adapted to be mounted within the carbureter ofl'take, the means securing which will also serve as a packing between the carbureter discharge and the engine manifold, thus insuring a tight joint at this point through means forming a part of our said attachment.

The invention consists primarily in a carbureter attachment embodying therein a base having a central opening therein of.

substantially the same diameter as the carbureter oiftake pipe, a reticulated conical distributor having its apex directed toward said opening in said base, the dimensions of the base of said distributor being smaller Patented Apr. *7, 1914.

than those of said opening in said base, and

divergently arranged supports of small dimension extending from said base and secured to said distributer, whereby said distributer is spaced away from the o ening in said base and clearance is aii'ord ed about said distributer; and in such other novel features of construction and combination of parts as are hereinafter set forth and, de-

scribed, and more particularly pointed outin the claims hereto appended.

Referring to the drawings Figure 1 is a view showing a portion of the ofl'take lead of the carbureter, and a portion of the engine manifold, our attachment being shown in position relative thereto; Fig. 2 is an elevation of our attachment removed from the carbureter offtake; Fig. 3 is a top View of our attachment; and Fig. 4 is a detail sectional view of the distributer, illustrating the means of mounting same in relation to the base. 7

Like letters refer to like parts throughout the several views.

In the embodiment of our invention shown in the drawings, a indicates a base consisting of a flange adapted to seat between the flanges of the carbureter offtake and the manifold intake. The configuration of this flange should be such as to conform to the flanges upon the carbureter, and upon the manifold, and ,while in the accompanying drawings we have shown a circular flange, it is understood that the configuration of this flange is immaterial. Centrally thereof the base a is provided with anopening 6, the diameter or dimensions of which coincide with the area of the carbureter. oiftake, indicated at o and the manifold intake indicated at d.

Carried by thebase a and spaced away therefrom a distance sufficient to leave clearance thereabout, is a distributer 6 consisting of a hollow cone open at the bottom and having its apex directed toward the opening I) and substantially centrally thereof. The distributer e is preferably made of sheet metal having a number of small openings e therein, although if desired any other reticulated material may be used, the effect of which will be to deflect a portion of the mixture flowing from the carbureter to the engine toward the sides of the manifold intake while permitting a portion thereof to pass through the openings, thus causing diversified currents about the distributer and a slight retardation at some points thereof and not at others while causing acceleration of a portion of the mixture at the base of the distributer. p

The diameter or dimension of the base of the distributer e is considerably smaller than that of the opening I) thus affording clearance about said distributer, and between 'it and the walls of the engine manifold d.

' The number and arrangement of the open ings e are such as to approximate in the aggregate area, the area of the base of the distributer, thus insuring a capacity of the distributer sufiiciently great to avoid any material obstruction to the flow of the mixture from the carbureter to the manifold. This distributer is supported from the base a by a plurality of fine wire supports 7, converging from the base 0, toward the base of said-distributer; e, the object ofthese supports being merely to rigidly hold the distributer eat the desired distance from the base a without having any confining effect upon, or offering any substantial resistance to the flow of,.the mixture-. To avoid displacement of the distributer, we attach the, supports f thereto in a manner to not only hold the distributer with relation to the base,

but to hold it in a .mannerto avoid the stresses of use from disconnecting said distributer from its supports. To secure this result, we provide the distributer adjacent the base thereof with oppositely disposed openings through which the wire supports f pass, the ends of said supports being secured to the base. By this construction it is practically impossible for the distributer to be'accidentally disconnected from its supports and the distributer is held with the desired rigidity so as to withstandthe effect of the suction about same caused by the engine.

When the throttle valve 9 of the carbureter is turned as shown in full lines, Fig. 1, to accommodate the carbureter to low engine speeds, there is a tendency of the mixture to flow toward and adjacent the wall of the manifold d. y

To insure the desired operative effect of the distributer e, particularly at low engine speeds, we provide the base a with the vanes or deflectors h h, projecting above said base and directed upwardly and inwardly so as to deflect a portion of themixture toward said distributer and prevent strat-ification adjacent the wall of the manifold intake. Thesev vanes or deflectors will also at all times set up cross currents, thus aiding in the agitating and commingling of the mixture while flowing from the carbureter to the manifold. The vanes or deflectors h it are positioned upon opposite sides and above the axis of the pivots of the butterfly valve 9 so that the mixture when said valve is partially closed, will have a general direction toward said vanes or. deflectors.

To permit the application of our attachment without material loss of space or unnecessary multiplication of parts, we form'- the base a of a soft metal having a series of continuous parallel corrugations z' extending the attachment is in place in the duct formed.

by the carbureter ofi'take and the manifold intake, the distributer 6 will be positioned substantially axially of, above, and spaced away from, the carbureter ofl'take 0, with the apex thereof positioned substantially axially of said ofi'take. The opening 6 in the base a will be in substantial alinement with that of said ofltake 0. Hence there will be no appreciable obstruction of the manifold intake excepting by the distributer a, the position of the openings of which will give suflicient capacity to avoid any substantial retardation of the flow of the mixture. As the mixture flows from the carbureter to the manifold, a portion thereof will impinge upon the outer surface of the distributor and be deflected outwardly, and a portion thereof will pass through the openings in said distributer. If any large globules of hydrocarbon be carried in suspension, their impact with the distributer will have the efl'ect of breaking them up and thus bring the entire body of hydrocarbon into more intimate relation with the air forming a part of the mixture. The inverted conical will offer substantially no resistance to the flow of the gaseous mixture. The segmental vanes or deflectors h h will also have a tendency to set up cross currentswithin the manifold intake between the distributer and the carbureter, these deflectors having their highest efficiency when the throttle valve of the carbureter is partially closed, under which conditions they Will have the effect of directing the mixture toward the axis of the manifold intake d or against the distributer e, a condition which will insure the eflicient operation of the device whether the engine be run at either high or low speed. 1

It is to be noted that our attachment com prises no moving parts and offers substantially no resistance to the flow of the gaseous mixture, while breaking up the column thereof and agitating it by means of cross currents in a manner to thoroughly mix the entire volume of hydrocarbon and air, prevent stratification thereof, and secure a more intimate contact of the hydrocarbon with the air in a manner to secure a mixture having higher combustion "alues. By reason of these conditions, the quantity of hydrocarbon entering into the mixture may be reduced and fouling of the engine cylinder, or parts appurtenant thereto, may be minimized.

It is not our intention to limit the inven tion to the precise details of construction shown in the accompanying drawings, it being apparent that the general design may be varied without departing from the spirit and scope of the invention.
